It rarely happens because they start you with (80? not sure) durability now, in 2k11 it was probably at 50 or smth. My player got an injury at one point as well, can't remember what but he was only out for 2 days or smth.
I remember in 2k11 having my mycareer injured for over a year, that was pretty cool imo. The part where my console froze every time after that game and i had to start over was kind of a bummer though.
2k11 was freezing and glitching all over the place, it's funny how people seem to have forgotten about that. They put it on a pedestal and make it untouchable, it was my favorite as well but some people here glorify it a bit too much. I'm not talking about the guy i'm quoting btw, just a general impression i've had during my time on these boards.
